Vortex fan install Wiring Questions

Hello, our entry level trailer came with no bathroom fan so I added the same hengs fan. It's a little noisy but we use it mostly when we showed so it doesn't really matter.

Do you already have the fan installed? If not and you have no existing fan you may have to tap into a nearby light. If you do have an existing fan or it is prewired it will be easier.

The good thing is it is only 12v so, while you don't want to short the wires together, it won't kill you if you do.

All the switch does is interrupts the flow of electricity. Run a wire (2 wire) from the fan area to the switch area. The 12v switches generally accept some kind of wire end as shown in the pictures I. The thread. These connectors are available in any auto parts store or Wally World. They generally crimp on so no soldering is required.

What you want to do is interrupt the positive side of the 12v feed, run it to the switch rather than directly to the fan, then from the other side of the switch, run it back up to the fan. Consider it kind of like driving and taking a detour through the switch rather than directly to the fan. Run the negative side (ground) directly to the fan.

One of the reasons I bought this fan is it installs very easily into the existing vent. It is a very easy install and if you take your time it will be no problems.

Pm me if you have any questions or need additional help.

Good luck!

My trailer already has the Vortex installed it got soaked and shorted out when the roof vent got cracked.

I'm guessing i need to eliminate the black and white wires from the push button switch and run those to the new wall switch.

Just the hot wire to the switch and leave the ground wire unswitched.

I have attached a couple of photos from the thread i originally seen this in.

Do i need to bypass the black and white off the black switch completely and snake them to the new switch or just tap them all together? i can't tell where this guy tapped the wires from.

Wires from fan to switch

Fan assembly

You don't need to bypass the switch on the fan itself, just turn it on and leave it on. Run the positive (hot) wire to the new wall switch first then back up to the hot side on the vortex fan itself.

Perfect thanks for the help electricity isn't my best skill set.

Let us know hot it goes.

I'm not sure why they needed to run two wires down the wall to the new fan switch. You normally only need to pull one black wire from the new switch to the new fan wire. (with a wall switch my option would be to bypass the new fan pushbutton switch) The 12v + is already at the bottom of the existing light switch and needs to be jumpered to the new fan switch. The 12v- just gets connected in the ceiling.

I'm wanting to bypass the switch with my idea I have a new double on off switch to replace the single one now. So you're saying wire fan as is factory run hot to top of switch and run load wire back to ground on fan?

I assumed from the original post there was no existing wall switch. Therefore, he would need a wire going to the switch and one coming from the switch to the fan. Not two SETs of wires, just two wires.
